A very nice photo
Is it possible to identify this Whittleia form this picture? I found it in sanddunes of Hungary, Kiskunhalas, 27.03.2021
I gave this question to Thomas Sobczyk, a well known specialist of Psychidae. And he answered:
"nein. Sehr wahrscheinlich handelt es sich um W. undulella. Ohne genaue Untersuchung des Exemplars, nur nach Foto, ist eine sichere Determination nicht möglich."
[No. It is very likely that it is W. undulella. A reliable determination is not possible only after a photo and without a detailed examination of the specimen.]
Did you collect a specimen, that could be examined?
